[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1

[0030] Reference Figures 1 to 7 This is the first embodiment of the present invention. This embodiment provides a steel pipe cutting positioning and fastening device. The steel pipe cutting positioning and fastening device includes a main body component 100 and an adjustment component 200. The two work together to adjust the clamp spacing according to the length of the steel pipe to adapt to steel pipes of different lengths and specifications, so as to achieve stable fixation and expand the application range of the clamp in various steel pipe cutting tasks.

[0031] The main component 100 includes a fixing ring 101, a support frame 102 fixed to the bottom of the fixing ring 101, and a support leg 103 fixed to the bottom of the support frame 102.

[0032] The steel pipe is fixed by placing it inside the fixing ring 101 and then fixing it by contracting the fixing ring 101. The fixing ring 101 is existing technology and will not be described in detail here. When different steel pipes need to be fixed, the distance between the two fixing rings 101 can be adjusted to accommodate steel pipes of different lengths. The support frame 102 is used to support the fixing ring 101 and prevent the fixing ring 101 from shifting. The support leg 103 can support the support frame 102.

[0033] Adjustment component 200 is disposed on support frame 102 and includes adjustment member 201. Adjustment member 201 includes adjustment plate 2011. Adjustment plate 2011 is fixed to one side of support frame 102. A rack 2012 is fixed to one side of adjustment plate 2011. A gear 2013 is disposed on one side of rack 2012. Rack 2012 and gear 2013 mesh.

[0034] When the spacing of the fixed rings 101 needs to be adjusted, one of the adjusting plates 2011 is moved. At this time, the adjusting plate 2011 can drive the support frame 102 to move. Simultaneously, the movement of the adjusting plate 2011 can drive the rack 2012 to move. When the rack 2012 moves, it can drive the gear 2013 to rotate. At this time, the rotation of the gear 2013 can drive the other rack 2012 to move. The movement of the other rack 2012 can drive the other adjusting plate 2011 to move, so that the spacing of the two fixed rings 101 can be adjusted at the same time.

[0035] Example 2

[0036] Reference Figures 2-7This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, the adjustment component 200 also includes a positioning component 202, which includes a positioning box 2021. The positioning box 2021 is sleeved on the outside of the gear 2013, and the positioning box 2021 and the gear 2013 are rotatably connected by a bearing.

[0038] The adjusting plate 2011 and the rack 2012 are both located inside the positioning box 2021 and are slidably connected to the positioning box 2021. The positioning box 2021 can support the gear 2013 and prevent the gear 2013 from shifting.

[0039] Specifically, a slider 2022 is fixed on one side of the rack 2012, and a groove 2022-1 corresponding to the slider 2022 is opened in the positioning box 2021. The slider 2022 slides within the groove 2022-1.

[0040] When the rack 2012 moves, it can drive the slider 2022 to move within the groove 2022-1, thus supporting the rack 2012 and preventing it from shifting during movement.

[0041] Specifically, a coil spring 2023 is fixed to the bottom of gear 2013, and one end of the coil spring 2023 is fixed to the inner wall of positioning box 2021.

[0042] When the rack 2012 moves to adjust the distance between the fixed ring 101 and the gear 2013, the rotation of the gear 2013 can apply a torsional force to the coil spring 2023. When it is necessary to return the fixed ring 101 to its original position, the force of the coil spring 2023 can drive the gear 2013 to rotate, thereby allowing the fixed ring 101 to return to its original position.

[0043] Specifically, the adjustment component 200 also includes a movable component 203, which includes a limiting plate 2031. The limiting plate 2031 is fixed to the inner wall of the positioning box 2021, and a limiting block 2032 is provided on the top of the limiting plate 2031.

[0044] A limiting groove corresponding to the limiting block 2032 is provided on the limiting plate 2031. When the spacing of the fixing ring 101 is adjusted to the specified distance, in order to prevent the adjusting plate 2011 from moving on its own and causing the spacing to change, the limiting block 2032 is engaged with the limiting groove to limit the adjusting plate 2011 and prevent the adjusting plate 2011 from moving on its own. After the adjusting plate 2011 is fixed, the steel pipe can be clamped and fixed, which is convenient for subsequent cutting.

[0045] Specifically, a movable column 2033 is fixed to the top of the limiting block 2032, and a guide frame 2034 is sleeved on the outside of the movable column 2033. The movable column 2033 and the guide frame 2034 are movably connected.

[0046] A guide bar is fixed to the top of the movable column 2033, and a guide groove corresponding to the guide bar is opened on the guide frame 2034. When it is necessary to release the limit on the adjustment plate 2011, the guide frame 2034 is moved. At this time, the guide frame 2034 can drive the guide groove to squeeze the guide bar and make it move. The movement of the guide bar can drive the movable column 2033 to move. At this time, the movement of the movable column 2033 can drive the limit block 2032 to move and separate from the limit groove, thereby releasing the limit on the adjustment plate 2011.

[0047] Specifically, a movable rod 2035 is fixed to the top of the guide frame 2034, and a pull rod 2036 is fixed to one end of the movable rod 2035.

[0048] Moving the pull rod 2036 can drive the moving rod 2035 to move. The movement of the moving rod 2035 can then drive the guide frame 2034 to move, thereby allowing the limiting block 2032 to move and separate from the limiting groove.

[0049] Example 3

[0050] Reference Figures 1 to 7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0051] Specifically, the adjustment component 200 also includes a pull member 204, which includes a connecting post 2041. The connecting post 2041 is fixed to one end of the pull rod 2036, and a handle 2042 is fixed to one end of the connecting post 2041.

[0052] By pulling the handle 2042, the connecting column 2041 can be moved, and when the connecting column 2041 moves, the pulling rod 2036 can be moved.

[0053] Specifically, a positioning plate 2043 is fitted on the outer side of the connecting column 2041, and the connecting column 2041 and the positioning plate 2043 are movably connected.

[0054] The positioning plate 2043 is fixed to one end of the adjusting plate 2011. The positioning plate 2043 can support the connecting column 2041 and prevent the connecting column 2041 from shifting.

[0055] Specifically, a spring 2044 is fixed to one side of the positioning plate 2043, and one end of the spring 2044 is fixed to one end of the pull rod 2036.

[0056] When the handle 2042 is pulled, causing the pull rod 2036 to move, the pull rod 2036 can apply a compressive force to the spring 2044. Then, the limiting block 2032 separates from the limiting groove, which releases the limiting of the adjusting plate 2011. The adjusting plate 2011 can then be adjusted to the designated position. After the adjustment is completed, the handle 2042 is released. At this time, the spring 2044 rebounds, which causes the pull rod 2036 to return to its original position, thereby causing the limiting block 2032 to engage with the limiting groove, and thus limiting the adjusting plate 2011 again.

[0057] In use, the spacing of the fixing rings 101 is first adjusted according to the length of the steel pipe. The handle 2042 moves the connecting column 2041, which in turn moves the pulling rod 2036. The pulling rod 2036 moves the moving rod 2035, which in turn moves the guide frame 2034. At this time, the movement of the pulling rod 2036 applies a squeezing force to the spring 2044. When the guide frame 2034 moves, it can cause the guide groove to squeeze the guide strip and make it move. The movement of the guide strip can then move the moving column 2033. The movement of the moving column 2033 moves the limiting block 2032, causing the limiting block 2032 to separate from the limiting groove on the limiting plate 2031, thereby releasing the limitation on the adjusting plate 2011.

[0058] Next, one of the adjusting plates 2011 is manually moved. The movement of the adjusting plate 2011 will cause the support frame 102 to move. At the same time, the movement of the adjusting plate 2011 will cause the rack 2012 fixed on one side to move. The movement of the rack 2012 will cause the slider 2022 to slide in the groove 2022-1 in the positioning box 2021, which will support the rack 2012 and prevent it from shifting. The movement of the rack 2012 will cause the gear 2013 to rotate. When the gear 2013 rotates, it can apply a torsional force to the coil spring 2023. The rotation of the gear 2013 will cause the other rack 2012 to move. The movement of the other rack 2012 will cause the other adjusting plate 2011 to move, thereby adjusting the distance between the two fixing rings 101 simultaneously until the distance can adapt to the length of the steel pipe to be fixed.

[0059] After adjusting the spacing of the fixing rings 101 to the specified distance, release the handle 2042. The rebound force of the spring 2044 drives the pull rod 2036 back to its original position. The pull rod 2036 then drives the related components back to their original positions, causing the limiting block 2032 to re-engage with the limiting groove, thus limiting the adjustment plate 2011 and preventing it from moving on its own. At this point, the steel pipe can be placed inside the fixing rings 101 to prepare for clamping and fixing the steel pipe, facilitating subsequent cutting operations. If the spacing of the fixing rings 101 needs to be adjusted again, for example when changing to a different length of steel pipe, repeat the above operation of releasing the limit of the adjusting plate 2011. After releasing the limit of the adjusting plate 2011, the force of the rotating spring 2023 drives the gear 2013 to rotate. The rotation of the gear 2013 drives the rack 2012 to move. The movement of the rack 2012 drives the adjusting plate 2011 to move, so that the two fixing rings 101 return to the initial spacing position. Then the spacing adjustment operation can be performed again according to the new steel pipe length.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
